Please solve my question
I had found *experimentally* that
there are difference about the handling of "CTS"
in Intel i8251A and NEC uPD8251A.

i.e.
  if "CTS (Clear To Send)" negation is occurred while sending,
  Intel i8251A *re*-send the data automatically *again*
  after next "CTS" assertion.
 
Is this specification of Intel i8251A ?

!= ?

Who is he ?
